I don't know where you got that idea from.
The standard power supply for the WS19 Truck & Ground station was the 6 Volt 85 Amp hour battery, issued in two pairs along with Switchboard, Charging, No.5 and a 300 watt charging set so that one pair could be recharged while the other was in use. This was standard for Jeeps and small vehicles (plus Land Rovers later on) and some trailer mounted installations.
Larger vehicle installations (LCV, ACV, etc.) used the 6V 170Ah batteries as size/weight was not such a problem. (Also, the various command vehicles would be making rather more use of the transmitter, with an associated increase in power drain.)
Anything with the WS19HP fitted required 170Ah batteries since the RF Amplifier No.2 drew 24 Amps (Mk.1 or Mk.2) or 18 Amps (Mk.3) on transmit and this would be far too much (especially when you add the 10 - 12 Amps drawn by the WS19 driving it) for an 85Ah battery - it's discharging at around the 3 hour rate which is a very bad idea.
Units near the front line (where noise was a problem and charging sets could not be used, plus the WS19HP Jeep install where there was no room for a second set of batteries and a charging set) would rely on central charging of batteries and daily delivery of replacements along with ammunition, POL and rations, etc. (That was what the 1260 Watt charging sets were used for.)
